We have experience problems using O2 ashers on chrome.  Be careful.

Just to re-visit a wise warning from a recent poster, Piranha etch (at
110C or not) is seriously hazardous, and we need to be flagging up
safety advice when suggesting stuff.

I don't see a problem with using an oxygen asher, and if there is no
problem (anyone?), do that instead, Mikas!
